To aZZ/Lvhomz't may concern: l

Be it known that I, BYRON E. VIELE', a

Grinnell, in the county of Poweshiek and State of Iowa, have invented certain new and useful Improvements in Turntables;

and I do hereby declare the followingtobe a full, clear, and exactv descrip-tion of the invention, such as will enable others skilled in the art yto whi h itV appertai'ns to make v and use the same.

of the following description.

My invention relates to improvements in turntables especially adapted for use yin roundhouses in directing locomotives to different points in the roundhouse. f

An important object of this invention is to provide an apparatus of the character described having means carried by the turntable to rotate the same. Y

A further object of the invention is Vto provide a turntable mounted. on a centrally disposed pivot and having connection with a single wheel operating on a circular track, said wheel being adapted to be rotated, to in turn rotate the apparatus. f A further object of the invention is to provide a device of the character described which is efiicient in use, simple to and of highly simplified construction. y Other objects andadvantages of the in vention will be apparent during the course In the accompanying drawings, formin a part of this specification, and in whic like numerals are employed to designate like parts throughout the same, f Figure 1 is a vertical longitudinal section, taken through the apparatus, y Fig. 2 is a front elevation of the propelling wheel of the turntable, showing the saine journaled through a slotted bearing,

Fig. 3 is a plan view of a turntable emv bodying my invention, v

Fig. iis a plan view of a turntable embodying my invention, partsthereof being" broken away, and v Fig. 5 is a plan view propeller mechanism.

In the drawings, wherein for the purpose of illustration, is shown the preferred .em-

of a portion of the bodiment of my invention, the numeral 10" designates a circular pit havinga base 11 disposed centrally thereof and supporting a pivot 12. A turntable, generically designated by the numeral 13, is rotatably mounted on the pivot 12 and is comprised of a operate Y stoutv framelt and a horizontal structure having lrails 17 upon its upper surface.

A' circular track 18 arranged in the vpit Patentd'oeaia, 1920. l

disposed at right angles to the motor 20. A i

kbevel gear 22 is disposed on one end ofthe,

crank shaft- 22 and has engagement with a second bevel gear 23. The crank shaft 22 operates in bearing members 24, which may be of `any suitable type. A vshaft 25, eX-

tending longitudinally of the turntable is Y connected with the bevel gear 23 and has arranged on its opposite ends a wheel 26,- adapted to partake of engagement with` the circular track 18. The inner end portion of the longitudinally extending shaft is journormallyhold the shaft 25 in a horizontal position., Elongated 'openings 31, eXtend-V y A ing vertically of the bearing box 29, permit vnaled in a Ibearing member 27, Awhilethe reciprocatory bearing member 28 f arranged in a boX'29. A spring 30 serves to of the shaft 25 partaking of a reciprocatory movement. As clearly shown inV Fig. 5, the

bearing box 29 is secured to the side of the 4 turntable, as at 32. Particular attention is called'to the fact that the spring 30 serves to retain the wheel 2G firmly in contact with A locomotive is run/on the tracks 17 un-v der its own power if possible. -To vrotate the turntablefto the desired point, the motor 20 is operated, which in turn operates the wheel 26, having engagement with the tracks 18. It will be thus apparent that the travel lof the wheel 26 will cause the turntable to partake of a rotary movement in the desired direction.

be seen that the wheel 26 is" forced into firm contact witlr the circular tracks 18 by the,

weight ofthe turntable and the spring 30. 'While I have kshown andy described vthe it will be k the circular rail 18. In practice, the motor iosj With reference to Fig. 1 it will I, understood that I mayjmake such minor changes in arrangement vand construction of lpartsas Will remain Within the spirit ofthe x Y Y I"tion vin the bearing member, said bearing 20 Vinvention and the appended clairr." f K i Having `thus .described my. invention, what( v l I claimJist vlO n f A turn table comprisingja lpivot member mounted in a pit, a tableipivoted upon the pivot member, a circular track located in l the pit below the table, a'motor .Xed to the table, al shaft ,journaled' upon .the table,
